Identify the name of reaction if carbonyl group of aldehydes and ketones is reduced to methylene group on treatment with hydrazine followed by heating with sodium hydroxide in ethylene glycol.

Step-by-step solution

Wolf-Kishner Reduction universally reduces carbonyl groups of aldehydes and ketones to methylene groups using hydrazine followed by sodium hydroxide in ethylene glycol. The reaction proceeds via hydrazone formation and base-promoted nitrogen extrusion to yield the alkane. Among the choices: Option A describes this reaction correctly. Clemmensen reduction uses Zn(Hg) and HCl; the Stephen reaction converts nitriles to aldehydes; and the Étard reaction oxidizes methyl groups to aldehydes. The transformation is achieve
